  • Purpose: Mountain biking as a sport and recreational activity has grown rapidly over the previous two decades. The purpose of this study is to analyze differences of leisure satisfaction by demographic characteristics of mountain bike participants. Research design, data, and methodology: To accomplish the purpose, the study employed purposive sample method among nonprobability sampling and collected data from 300 participants. Of collected data, 288 responses were analyzed excepted for uncompleted responses. To analyze data, study utilized statistical techniques including descriptive statistics, reliability analysis, independent-sample t-test, and one-way ANOVA, and to verify difference between individual groups in relation to significant results, Duncan's multiple range was conducted. Results: Findings indicated no differences of leisure satisfaction by gender. Similarly, education level and occupations have not influence leisure satisfaction. Yet, differences of leisure satisfaction by participation frequencies were observed. Of participation frequencies, participants riding 5 times a week were more satisfied with MTB participation than the other groups participating less 3 times a week. Conclusions: The findings provide a couple of insights in terms of promoting MTB participation. In specific, results indicated that MTB would be attractive sports that is able to appeal huge populations regardless of their education and occupation. Furthermore, consistent participation is judged an effective way to increase psychological, educational, and social satisfaction. In this sense, regional MTB clubs could play a salient role in motivating riders to more participate in MTB. Hence, establishing strategies for encouraging club activities are needed.

  • Purpose : This study examined the effects of work environment and organizational culture on tertiary hospital nurses' turnover intention. Methods : A cross-sectional design was used, with a convenience sample of 371 hospital nurses from 16 units of three tertiary hospitals in South Korea. Data were collected through a self-report survey conducted during September and October 2016.

Results : A total of 43.7% of the participants were identified as having turnover intention within 1 year. Factors related to turnover intention among hospital nurses were age, marital status, and total clinical career. Furthermore, a relationship-oriented organizational culture showed a negative association with turnover intention. Conclusion : These findings suggest it is important to provide appropriate motivational programs and incentives for nurses according to their clinical career to decrease turnover intention. Moreover, establishing a relationship-oriented organizational culture will also help to reduce the turnover intention of tertiary hospital nurses.

Conclusions: Psychological well-being was related to positive psychological capital and role conflict. Future efforts are needed to improve positive psychological capital and psychological well-being of dental hygienists and reduce role conflict.

  • Purpose: We investigated the effects of music on pain, blood pressure, and pulse in patients with chronic back pain. We tried to find some change of satisfaction of treatment and a sense. Method: We recruited total 30 patients with chronic back pain, who had pain from lumbago for more than six months. Subjects received electrotherapy and electrotherapy with music one at a time during me test, and subjects received one in the morning and the other one in the afternoon. We compared the test results between the electrotherapy and electrotherapy with music. Visual Analogue Scale was used to check the effect on pain. Blood pressure and pulse were checked, too. The gathered informatio was analyzed by t-test, independent sample t-test, and chi-square test. Results: There was statistically not significant difference between electrotherapy and electrotherapy with the music in VAS(Visual Analogue Scale)(p>0.05). There were statistically some significant differences between two groups in systolic pressure, diastolic pressure, and the pulse(p<0.05). Subject group showed statistically higher scores of satisfaction(p<0.05). There was significant difference between two groups(p<0.05) in the tingling and vibration sense. Conclusion: we found that the lumbago patients who are treated by electrotherapy with the music did not have additional difference in relief of pain, but electrotherapy with music can get better effects on their blood pressure, the pulse, satisfaction, and tingling-vibration sense. This means that the patients receive their treatment comfortably with rest. Therefore, We consider that it is desirable to play music to lumbago patients to offer the better treatment service to the patients.

  • Purpose: This study was conducted to identify the effects of a prepared childbirth education on the knowledge and delivery participation levels of the spouses of primiparas. Method: The study's subjects were a convenience sample of 126 spouses, consisting of an experimental group of 74 educated for prepared childbirth for 10 hours. This study was measured by using a 41-item measurement instrument for knowledge of childbirth that was devised from Kang's(1981) instrument and a 23-item measurement instrument for measuring delivery levels which was developed through clinical experiences. The data gathered as analyzed by using SPSS WIN10.0. Result: There were no significant differences between the experimental group and the control group in homogeneity concerning the general characteristics of the spouses of primiparas. The first hypothesis, which stated that the level of knowledge of childbirth in the experimental group who received prepared childbirth education would be higher than in control group, was statistically supported by the Compared Independent Sample t-test(t=17.92, p=.000). The second hypothesis, which stated that the level of participation of delivery in the experimental group who received prepared childbirth education would be higher than in the control group, was also statistically supported (t=28.87, p=.000). The third hypothesis, which stated that there would be a correlation between the level of knowledge and the level of participation in the experimental group who received prepared childbirth education, showed a high positive correlation(r=.810, p=.000). Conclusion: The above results indicate that the increase of knowledge through prepared childbirth education in the spouses of primiparas has a high correlation with delivery partici- pation levels which engenders physical and moral support for primiparas at delivery. Additionally, a varied prepared childbirth education acts as an effective means to increase under- standing and support for primiparas couples who experience tension, anxiety and fear due to an unprepared delivery in Korea.
